Size of hide's

Hey everyone , as I mentioned before my BP is refusing food , going on 2 months now , no wait lose to date but was wondering if her hide is too small for her, would that cause her to stop eating ?
Was just thinking that if she is too big for her hide that maybe she would stop eating to diminish weight gain , just a thought.
Thanks for anyone that helps .

The tighter the fit the better.

The hide should be tight but the snake should be able to fit their whole body under it. If they are sticking out from under it along the sides it's too small. If it isn't touching on at least three sides, it's too big. A snug fit that the snake can touch with as much of their body as possible is ideal.

One thing to also consider is the opening. If your snake is scraping her scales on her back to get in its probably time to adjust.
